Associate Degrees & Certificates
Diesel Mechanics Technology
Roadmap
Overview
Certificate
PURPOSE: The Diesel Mechanics Technology curriculum is
designed to introduce the fundamentals of diesel equipment
repair and provide instruction in hydraulic systems, welding,
diesel engine overhaul and tune-up, electrical circuits, power
train maintenance, and fuel injection. The Diesel Mechanics
Technology program will give graduates a practical background
in basic diesel equipment technology principles. The curriculum
provides practical training and the option of on-the-job
experience through cooperative education. The demand for
trained diesel mechanic personnel and technicians is increasing.
OCCUPATIONAL OBJECTIVES: The Diesel Mechanics Technology
curriculum prepares graduates for employment in any of
the following occupations: Diesel Equipment Repair, Diesel
Truck Repair, Supervisor, Shop Foreman, Heavy Duty Repair,
Purchasing Agent, Salesperson, Power Train Repair, Fuel Injection
Repair, Diesel Engine Repair, and Automotive Diesel Repair.
PROGRAM NOTES: Students are strongly encouraged to meet
with the program head either before registering for their first
semester or early in their first semester of study. Students will
be required to furnish clear lens safety glasses, leather work
footwear, and proper clothing for working in the lab.

COMPUTER COMPETENCY REQUIREMENT: Students in
this program will meet the college’s computer competency
requirement by successfully completing ITE 115. Students can
also meet this requirement by passing the college’s computer
competency exam, administered in the testing centers on each
campus, in which case they will receive college credit for ITE
115. Students not passing the computer competency exam may
retake the exam only once.
